It's never been about favorite rounds for me as much as favorite hunting loads. For my typical moderate range hunting the 6.5 has nothing to compete with a 7-08 shooting a 120 BT over 3000fps or a .270 shooting a 150 partition at 2900 fps. The 6.5 is designed to take advantage of the high BC and sometimes that just doesn't matter.
How about a 120 gr. BT at 3000+ fps?
